Struct wasmer_types::MemoryType

pub struct MemoryType {
    pub minimum: Pages,
    pub maximum: Option<Pages>,
    pub shared: bool,
}

A descriptor for a WebAssembly memory type.

Memories are described in units of pages (64KB) and represent contiguous chunks of addressable memory.

Fields

minimum: Pages

The minimum number of pages in the memory.

maximum: Option<Pages>

The maximum number of pages in the memory.

shared: bool

Whether the memory may be shared between multiple threads.

Implementations

impl MemoryType

pub fn new<IntoPages>( minimum: IntoPages, maximum: Option<IntoPages>, shared: bool, ) -> Self

where IntoPages: Into<Pages>,

Creates a new descriptor for a WebAssembly memory given the specified limits of the memory.

Trait Implementations

impl Archive for MemoryType

where Pages: Archive, Option<Pages>: Archive, bool: Archive,

type Archived = ArchivedMemoryType

The archived representation of this type.

type Resolver = MemoryTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for MemoryType

fn clone(&self) -> MemoryType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<MemoryType, __D> for Archived<MemoryType>

where Pages: Archive, Archived<Pages>: Deserialize<Pages, __D>, Option<Pages>: Archive, Archived<Option<Pages>>: Deserialize<Option<Pages>, __D>, bool: Archive, Archived<bool>: Deserialize<bool, __D>,

fn deserialize(&self, deserializer: &mut __D) -> Result<MemoryType, __D::Error>

Deserializes using the given deserializer

impl Display for MemoryType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for MemoryType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemoryType

fn eq(&self, other: &MemoryType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S: Fallible + ?Sized> Serialize<__S> for MemoryType

where Pages: Serialize<__S>, Option<Pages>: Serialize<__S>, bool: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
